Disabling DTP Port Security VACLs PVLANs PACLs DHCP Snooping Disabling VTP Question 2 of 21 3. Which of the following statements about Loop Guard and Root Guard are FALSE? Select THREE answers. Loop Guard can be enabled on a switch that also has Root Guard enabled Loop Guard detects Root Ports and Blocked ports, and ensures they continue to receive BPDUs Loop Guard cannot be enabled on a switch that also has Root Guard enabled Loop Guard detects Root Ports and Designated ports, and ensures they continue to receive BPDUs The Root Guard feature prevents a port from becoming a Root Port, thus ensuring that the port is always a Designated Port The Root Guard feature prevents a port from becoming a Root Port, thus ensuring that the port is always a Blocked Port Question 3 of 21 4.
